The term "fat leg" is pretty self-explanatory, but do you know the difference between stocking up and cellulitis?

Many horses will "stock up" with subcutaneous edema (fluid swelling) in two or more legs (usually the hind limbs). Stocking up generally results from a significant decrease in exercise and usually resolves as the horse starts exercising again.

Lymphangitis (or vasculitis, big leg disease, staph infection, or cellulitis), however, is a bacterial infection and a dramatically different condition. While its causes may vary, it’s easy to spot once it sets in. The swelling will be extreme, hot, very painful to the touch, and the horse will be depressed due to the fever and discomfort.

If you think your equine friend has cellulitis or even if you're not sure, we encourage you to seek professional help promptly. Your equine practitioner will make the best treatment recommendations, both to reduce swelling and to address any sort of bacterial infection that might be active or that could occur due to the edema in the soft tissue.

Remember when your parents used to tell you to wait 30 minutes after eating before going for a swim? Unlike us, horses can actually benefit from eating forage before they exercise, as it may help reduce the risk of gastric ulcers.

While a variety of things can contribute to the development of stomach ulcers (medications, diet, stress, etc.), one train of thought is that these areas of irritation result as a consequence of the acid of the stomach splashing against unprotected parts of the stomach lining. When a horse eats forage, the hay can help absorb some of that acid and thus reduce the risk of ulcer formation.

It is important to note that a forage meal (one comprised of long stem hay) provides the most benefit, while eating large volumes of concentrate feeds (such as oats, corn, or other cereal grains) can actually increase the amount of acid within the stomach.
As always, please be sure to consult with your vet regarding further diagnostics and treatments if you have concerns that your horse may have gastric ulcers.

Spring is almost here! Which means…it's time to schedule your equine companion to receive their spring vaccinations!

If you are wondering what vaccinations your equine friend should receive, the answer is — There are no “one size fits all” vaccine recommendations. A veterinarian who knows your animal and your management system is your best resource to recommend what vaccines your equine should receive and with what frequency!

While vaccination does not prevent disease in all circumstances, a good immunization protocol minimizes the risk of infection and remains an essential component of responsible ownership. A vaccination appointment is also the perfect opportunity for a yearly check-up of your equine friend and a great way to catch any health concerns early.

If you have yet to contact your veterinarian about scheduling vaccinations, we encourage you to do it soon!

Though we wish our horse doctors could be there for our equine friends in any emergency, the reality is that our horses' primary veterinarian cannot be available 24/7 and still juggle the needs of their own personal lives, health and happiness.

The most significant pain point for many veterinarians is caring for their clients during regular business hours and then also being on call for emergencies after hours. For single-doctor or small practices, this traditionally has been the case most nights of the week.

However, private veterinary practices and veterinary schools have more recently focused on developing new models for emergency care which ease the strain on individual practitioners. This includes the growth of emergency cooperatives where two or more practices in a geographic area work together to share after-hours care, as well as more emergency-only practices and the use of tele-triage services to address client concerns after normal business hours.

As equine veterinarians reevaluate what after-hours care looks like for their practices, the support of their clients is critical to creating a balance that works for both parties. If your horse doctor talks with you about changes in how after-hours care is delivered, we hope you’ll welcome the adjustments. This evolution of emergency care must take place in order for equine veterinarians to avoid burnout and continue to be at their best to treat all of your equine friends.

It’s not uncommon to find horses and ponies living well into their 20s and 30s, thanks to continuous advances in nutrition and health care.

Horse owners have a big impact as well and can help their horses thrive in their golden years through proper management practices like those illustrated in the graphic. But remember, although there is much you can do on your own to keep your older horse happy and spry, some conditions associated with aging require medical intervention.

Scheduling regular visits and keeping a good line of communication with your veterinarian will allow you to respond quickly to any ailments or injuries that could cause your horse a serious or prolonged set back. That means less worry for you, and a better quality of life for your old friend!

FUN FACT FRIDAY!

Are you familiar with the many adaptations that help your horse stay warm during the cold winter months?

🌾 Hindgut digestion of hay produces the most heat, acting as a small furnace inside of the horse. This is why free choice; good quality hay is so important in the winter.

💪 Horses have a huge muscle mass and muscle activity produces heat. This includes running and playing and even shivering if their body temperature starts to drop. It is important to remember that these activities also will result in a bigger caloric demand so free choice hay and in some cases, grain, is often needed.

🧥 To blanket or not to blanket is a constant debate but either way, as it starts to get cold your horse will grow a thicker coat. If you decide to leave your horse unblanketed you may notice that they look “fluffy”. This is due to a phenomenon called piloerection where the hair stands up to better trap air within. Two layers of the coat also help with warmth. The inner layer is softer and has air pockets to create an insulating layer. The outer layer is coarse and has oils that keep moisture from penetrating the insulating layer and keep the horse warm.

⚖️ Wild horses go into the winter heavier than ideal, and the fat serves as an extra layer of insulation. However, if a horse is going to be kept heavily blanketed and in a barn during the cold weather months this is unnecessary and can lead to obesity related issues.

🦵Their distal limbs (below the knees and hocks) are made of mostly bones and tendons, tissues that are resistant to the cold temperatures.

🦶The hooves have an alternative route of blood circulation through larger vessels that can be used in low temperatures. This is why horses can stand in snow without detrimental effects.

👃A horse’s nose has a robust blood supply and is rounded so that it is less susceptible to frostbite than a human’s nose.

Water remains as important for your horse in cold weather as it is in the summer. As a matter of fact, decreased water consumption in the winter is thought to be the primary inducing factor for impaction colic — although there are other predisposing factors such as poor hay quality, lack of exercise, internal parasites and dental problems.

Impaction colic is essentially constipation and most often includes the accumulation of hard, dry f***l material in the colon. The usual signs of impending impaction colic are depression, a decreased appetite, and decreased production and dryness of manure.

Studies demonstrate that you can increase your horse's winter water consumption if you provide access to heated water, but ONLY if that is the only source of water available. As always, if you have any questions about preventing colic in your horse, your equine veterinarian remains your best source of information!

EPM is widely considered the most important infectious neurologic disease of horses in North America and is caused by protozoal infection of the central nervous system. Horses are infected by consuming food or water contaminated with opossum s**t containing sporocysts.

Horses with EPM do not present a biosecurity risk to other animals because the disease is not transmissible between horses. An effective vaccine has yet to be developed, so the best preventative approach includes eliminating access of opossums to feed and water in order to minimize contact with opossum s**t and improving your horse's immune defenses by decreasing stress and optimizing health.

To learn more about EPM, visit the following resources:

As always, consult your veterinarian for more information and for advice tailored to your horse's specific circumstances.

💉 The literal “shot heard round the world”. It sounds like a horse received Flunixin or Banamine intramuscularly on an episode of last night? We would like to remind everyone that despite being labeled for intra-muscular use, horses should only ever receive this drug orally or intra-venously. Something that the folks at Yellowstone would need to be on the lookout for after this misplaced administration would be signs of gas and swelling under the neck or a painful injection site. Administering IM banamine to a horse can cause clostridial myositis and can lead to a serious infection that requires surgical and antibiotic intervention. Despite intervention, these infections can be fatal.

IS RAIN ROT A FUNGAL OR A BACTERIAL DISEASE?

Rain rot (or rain scald) is the common name for a contagious BACTERIAL skin disease called dermatophilosis. It's caused by the bacterium "Dermatophilus congolensis," which thrives during wet seasons and in geographical locations with high precipitation and humidity. It can also develop after horses have sweat under blankets or tack, and equines with compromised immune systems are more susceptible.

Why should you not mistake rain rot for a fungal disease?
Antifungal medications and topicals have no effect on the bacteria responsible for rain rot, therefore diagnosing the condition correctly is very important!

How does rain rot happen?
The bacteria infects the hair follicles and damages the hair follicle and shaft; the hair will then pull out in small clumps leaving pink skin or purulent scabs behind (pro tip: your horse will NOT thank you for picking at them!) If you do not address the factors that promote the right bacterial environment (for example, you always leave your horse to stand outside in the rain without shelter or the protection of a waterproof rug), rain rot can keep recurring. If left untreated, the condition can even progress to a point where it opens the door for more serious, secondary skin infections.

If you suspect your horse has rain rot, be sure to consult your veterinarian on the best treatment plan based on the severity of your horse's case. While there are a million products that can be found in your local tack store, your horse doctor may have cause to prescribe a specific course of action.

With each passing year, horses are living longer lives and many survive easily to 25 years of age or older. While this is good news, it also means that we need to be aware of changes that can occur with age in order to preserve the health and quality of life of our equine friends.

For example, Equine Cushing’s disease is one of the most common diseases of horses 15 years of age or older. This syndrome is better defined as Equine Pituitary Pars Intermedia Dysfunction (PPID) because it reflects the location within the brain that is abnormal. Clinical signs are associated with abnormally elevated hormone concentrations in the blood.

Equine Metabolic Syndrome (EMS) is another endocrine disorder that can affect mature horses and shares some of the same clinical signs as PPID. Although the two disorders feature some striking clinical similarities — most notably a predisposition to development of chronic laminitis — the underlying disease biology is quite different in each case. Successful management relies on proper diagnosis by your equine veterinarian first.

Our understanding of both conditions, especially EMS, is incomplete and evolving, but sufficient information is currently available to highlight some important similarities and differences for the interested horse owner. Consult your veterinarian for more information and work with them to develop the best wellness practices to ensure a healthy life for your mature horse.

While it’s a common equine emergency, esophageal obstruction (“choke”) can look alarming, especially if you've never seen it before. Unlike in human medicine, where choking refers to a tracheal (or windpipe) obstruction, choke in horses refers to an obstruction of the esophagus (the muscular tube that carries food from the mouth to the stomach).

Most commonly, choking occurs when horses eat concentrated feed too quickly without chewing appropriately, which results in a firm bolus lodged in the animal's esophagus. However, esophageal obstruction can also occur with hay or straw, hard treats, carrots, or nonfood objects. Poor dentition, which leads to inadequate chewing, is also a frequent cause of choke.

While common, choke can have serious consequences. So, be sure to call your veterinarian as soon as you notice signs of choke. A bad choke is fairly obvious to both veterinarians and horse owners, but a mild choke could be confused with an upper respiratory tract infection or colic.
